[The mechanisms of hemodynamic shifts in normovolemic hemodilution].
Normovolemic hemodilution is shown to activate adaptation mechanisms of the heart, regional circulation and microvasculature. This is accompanied by a decline in the total peripheral resistance, an increase in venous return and intensification of the regional tissue blood flow. An increase in the cardiac output is due to mobilization of the functional cardiac reserve and is not accompanied by intensification of the heart work. Accelerated pulmonary circulation in normovolemic hemodilution may lead to functional shunting and blood oxygenation disturbances in patients with anatomic and functional respiratory changes.
